CLASP FOR BOOKS.

SPECIFICATION forming part of Letters Patent No. 317,122, dated May 5, 1885.

Application filed August 25, 1884. (No model.)

1o so as to draw the said covers together.

My invention relates to this general character of clasp; and it consists in the combination, with a sliding bar or loop, of wire springs bent to form the support for the loop or bar, and to give motion, by a toggle action, to the same in drawing the covers together, or to liberate the clasp for opening the book when the springs are pressed upon.

In the drawings, Figure 1 is an elevation of the said clasp. Fig. 2 isa modification in the shape of the springs, and Fig. 3 is a section at the line a: m.

The plates a and b are adapted to be riveted upon or otherwise attached to the book covers. The plate a is provided with the hinge piece or pieces c, and the spring-wire d is united to these, preferably by passing through them.

The link or loop f is adapted to catch upon the clip-plate b. If the clip-plate b has two studs, e, upon it, as shown, then the linkf will have'a head to pass between them; bntif the plate I; has only one stud, then the part f will have a hole through it or be formed as a loop to catch over the said stud.

. The link or loop f is guided at its back end by a stud or wire, z. If this wiret' is upon the loop f, then the same will pass through a hole in the spring (1, as seen in Fig. 1; but if the wire 1' is upon the spring (1, as seen in Figs. 2 and 3,then the loop f will be tubular or hollow to receive the same. The spring d is coiled at d to increase the length and obtain greater flexibility by the length of wire, and the portions d of the wire are adapted to be grasped between the thumb and fingers, and the ends of the spring are connected to the link or loop f at the pivot 0, so that when the portions d of the spring are pressed upon 50 the link or loop f will be moved endwise by a toggle action to separate the same from the i stud or studs 6.

In Fig. 2 I have shown the wire (2 as bent into loops d to increase its length and render it snfficiently flexible. pivoted links Z intervening between the ends of the spring and the joint or pivot 0. natural expansion of the spring outwardly at the parts at will tend to draw down the link or loop f and close the book-clasp. The rej I verse action takes place when the clasp is pressed upon at its sides.

It will be apparent that the. loop or link f, Fig. 2, may be omitted, the ends of the spring itself being connected to each other, and catch- 55:

I claim as my invention- 1. The combination, with the clip-plates a b and stud e, of a loop or link, f, and the toggle-acting spring d, forming the support for 7 the loop or link, and the connection a between the spring and the clip-plate a, substantially as set forth.

2. The combination, withv the clip-plates a; i p p b, of the hinge connections a, the toggle-act; 75.

ing wire spring d, passing through the connections c, and coiled, as at d, and the loop or link f, connected to and supported by the r spring d, substantially as set forth.

3. The combination, with the clip-plates a so I), studs 0, and hinge-pieces c 0, of the toggleacting wire spring passing through said hingepieces, the loop or link f, connected with the ends of the spring, and the guide-wire 2', sub- I H ALFRED G. HAFELY.
